2 Chronicles 29:20-24

Early the next morning King Hezekiah gathered the city officials and went to the Temple of the LORD. They brought seven bulls, seven rams, and seven male lambs as a burnt offering, together with seven male goats as a sin offering for the kingdom, for the Temple, and for Judah. The king commanded the priests, who were descendants of Aaron, to sacrifice the animals on the altar of the LORD. So they killed the bulls, and the priests took the blood and sprinkled it on the altar. Next they killed the rams and sprinkled their blood on the altar. And finally, they did the same with the male lambs. The male goats for the sin offering were then brought before the king and the assembly of people, who laid their hands on them. The priests then killed the goats as a sin offering and sprinkled their blood on the altar to make atonement for the sins of all Israel. The king had specifically commanded that this burnt offering and sin offering should be made for all Israel.
